The DVS Guitar was developed to be a VST plugin based on a sampled guitar and includes Overdrive, Reverb and Flanging. It's good for leads and heavy sounds, and very realistic if your good with a pitch wheel controller.

If you’re looking for a way to get realistic guitar with fl studio 9, after not being impressed with Fl Slayer and not being able to get Real Guitar and Real Strat to work (possibly because you don't use a music keyboard), This will help you a lot.
